t 5 In carrying `thelfcurrent invention into effect,

according to one mededescribed by `Wayof examplewas applied tontafsuspendedyiurnace primary-Wall.' and `in Y,a .manner adapted t toprovide acavity orpassage lchamber zbetweenlthe primary .and secondarylwalls; for the accommodation of pipes or tubes, the primarywall is shownas ycom-` prising insulationblocks .I IJ, rlll hooked and lgeyed4betweenhorizontal,drietal-framemembers ll,` .Il t

carried `on"vertical, supporting posts or channels l2, l2,`oiwhichlonlyoneistshowmgby means of bolts`l3, I 3` which extend throughapertures in e t 2,377,528 t the metal-casing I4, such primary-wall alsoincluding intermediate insulation-blocks I5, I5 and an outer wallcomposed of insulation blocks I6.

Each horizontal, metal-frame member II, of general channelcross-section, has a longitudinal, upstanding flange I1 along its outerpart and a depending flange I8 along its inner part, flange I1extendingupwai'dly into a cavityy I9 along the outer lower part of thecorresponding blocks III, flange I8 `projecting downwardly into a slot2| in the top of the corresponding or next lower blocks IIJ intermediatebetween their inner. and

wardly from its lower edge a distance correspondng to that from thelower end of either slot 34 or 35 to the bottom edge of plate 21.

To reduce the weight of such abutment-plates each has its opposite,vertical edges recessed at 49, 49.

When plate 46 is in slot 34, and plate 21 is in slot`48 as presentedinjhiguregit,is'backed up and maintained in proper position by engagingthe edges of the plurality of registered projec- 'Jtions 36, 31, 38 and39, and also, when the companion plate 41 `is in slot 35, it issustained in outerv face's, the upper flange I1 convenientlyconstituting means forsecuring or holding in vposi- 'tion thestabilizing-plate vmembers to'be described below.

The vsecondary-wall, illustrated in Figures 1 and 2, is composed osuperposed,lthin,'building blocks, tiles or panels 22, 22, the upper andlower faces of which are formed or moulded with .mortice andftenon orother keyingv or interengagingmeansZB.

lThe blocks or tiles 22 are erected to constitute thesecondary-walllocated in appropriate spaced relationshipy forwardly` from` theprimary-wall block I0 and I5 so vthat an upright space or cavity 25 isprovided within which pipes or tubesA 29 for the conveyance of water orotherliquid or air or gas to be heated, are accommodated.Secondary-wall, relatively-thin, stabilizing members lor plates 21 .areprovided, preferably` at 28 and 9v to reduce weight, and aninwardly-extended,

apertured each of these'comprsesv flat metal-plate, as shown in Figure4, formed from sheet-metal which at one end has ,been shaped andstampedto providefa longitudinal hook-member .3l having -ari'extension'.32 projecting laterally from the downwardly-directed portionIof the hook, the. corresponding end of plate 21 having a` portion33projectedV therefrom laterally in the direction opposite to that lofpart 32. l

Hook 3l and its transverse extension' 32 are adapted to engagebehindthe`flange I1 `ofthe norizontai bar Il (Fig. 1i while the portion 33 7bridges thefront face of the corresponding, horizontal, `metalframe-'member `I I as shown in Figures l1 and 2 lying against the edgesof the two parallel flanges ofthe channel-member II.

Near itslfopposite" end, plate 21 has a pair of parallel slotsY 3 4, 35Yextended` downwardly from its upper edge and' the" plate is further cutand bent to providetwo sets of four-each of horizontallaterally-extended lugs3$,"31, 38, and 39 and 4I, 42, 43, and44,.alterna te lugs of each set pro- "jecting in oppositedirections fromthe vertical plane of the plate, 'one .edge of alllugs of one set beingin register with the corresponding edge of slot I34 and one edgeA of allofthe lugs of the other set being in the register with lthe adjacentedgeof the other slot 35, all as is clearly illustrated in Figure 4. y

As is fully shown, the distance between the ad jacent edges of the twogroups of lugs'is substantially the same as the thickness of the blocksor tiles 22 of the secondary-wall.

In addition; the portion of plate21lbetween the two verticalspaced'rows`-offlugs, has an opening 45 to accommodate the lateralkeying or interengaging means 24 `on the vertical edges of the blocks22(1iig.k 2). y

Each plate 2 1 is supplied with two abutmentplates 45 and 41, which maybe alike,'each having a central slot 48f Fig-` 5) vof a widthtoaccommodate lthe thickness'of plate 21 and extending upposition andbolstered up by contact with the edges lof the other group ofvertically-aligned lugs 4'I,' 42, 43 and 44. g In "erecting the primaryand secondary walls, the blocks are iltted together and between eachofthevertical joints of the secondary-wall and the appropriate joints ofthe primary-wall one of fthe plates 21 is introduced and hooked over theorrespondine flange. l1 as Yportrayed infieure l i ,e Theabutment-plate' 46 may be. already in por stion on plate 21 to lassistinbedding the added blocks v22 in position, and after thef'next blockshave been placed above those already in place, the abutment-plate 41 yisslippedinto position in iront of the secondary-,wall blocks. Q.

From`the` foregoing jitfwill be apparent4 that vthe secondary-wallblocksjare definitely positioned and stabilized atv their rear faces bythe plate 46 and tied at their vfrontiaces by the abutment-platen. K V

lThe erectionoiA the wall is continued with the insertion ofthe`stabilizing 'plates 21 intovertical joints at each course of thesecondary blocksand preferably inV the region of the" horizontal jointsthereof. f v

It will be appreciated that, by reason ofthe planes of the vplates 21lying. in the planes ofthe vertical joints of the blocks, the plates notnterfere with the vertical expansion and contraction of therespectivewalls andwill befunaifect'e'd by such movements,'while lateralexpansion and contraction movementsofr the wall are accommodated by thetransverse flexibility of the relatively-thin plates 21. v l f It willbe realized that,y by making .theabutment-plates 46 and 41 and the plate21 vmutually slotted,I either of the abutment-plates' can be removed bysliding it vertically and this is particularly vconvenient in referenceto the Vfront be stamped out 'with tongueswhich willv afford lsupportingareas equivalent tothe plate 43cm either side, or on both sides, of theplane of the plate 21. y 'V According to a modiiication, the plate"21`-niay be vformed with apertures through whichfwed'ges,

split-pins or the like may be introduced toserve as abutment members.

Further the hook means Bland 33 may breplaced by'vother `means adaptedto engage 'the framework of the primary-wall or engage the rear 'surfaceof the blocks or slots therein." i

Tnestabiiizing pistes in normal circumstances may be 'constructed ofverylight metal and may 2,377,528 be as thin as 11g", or less and the metalof which they are composed should be such as to have the necessaryheat-resisting properties to withstand temperatures` obtained in heater,drier or combustion chambers, for example, the metal employed for theseplates may be nickelchrome steel.

By making the stabilizing-plates Verythin, it

will be appreciated that very little space inthe cavity 25 is occupiedthereby, enabling th vertical pipes or tubes `2li to be installed in asclosely spaced relation as may be required, and further `itwill beunderstood that the thin plates offer no appreciable obstruction to thepassage of any gases which may be caused to pass upwardly or downwardlyin the space` 25 for `heating the tubes 26.` f

I The longitudinal and `transverse dimensions `of the plates maybevaried as desired and should be designed to accord withthe position andpurpose of the secondary-Wall to afforda doublecavitized wall or a`double Wallin which the secondary-wall is adjacent to or Vcontigucusftothe primary-wall. y The blocks of the secondary-wall may be of the samematerial asthose of the primary-wall or` `such may be ofa, differentmaterial according to requirements. i
